Abstract

Disclosed in the present invention is a method for a terminal to receive downlink control information from a base station in a wireless communication system. More particularly, the present invention comprises the steps of: receiving control information in a first area of a specific subframe on the basis of a first reference signal; receiving control information in a second area of the specific subframe on the basis of a second reference signal, wherein the first reference signal and the second reference signal are applied a same precoding.
